First Expedition [5]
As the expedition party made its way through the desert and fought many battles in their search for the Vanishing Dunes, they experienced a drop in their wariness.
It was just for a mere second, after a particularly powerful beast was killed, but that moment was fatal.
The great desert was that kind of place. It was filled with not only beasts, but natural traps that could activate at any time and pull practitioners into the depths of hell.
With the trying environmental conditions supporting them and making it so those traveling through the desert would have their senses weakened with time, these traps were more deadly than even the strongest of Divine Beasts.
When the Sand Wyrm that blocked their path fell, it created a massive hole in the sand, which, as it was filled, revealed the hidden mechanisms of a natural formation underneath it.
